Toa/ZZ whom t may con/cerra-r Beit known that I, WILLIAM F'. M A'.r'rns,a

citizen of the' United States, residing at Scranton, in the county ofVLackawanna and Statel of Pennsylvania," have invented certain new anduseful lImprovements 1n Gas-Generators;

and I do hereby declare the followingto be a full, clear," and exactdescription of the' invention, such as will enable others skilled in theart to which it appertainsto make andluse thev same.

ments in gas generators orapparatus, morev especially for makingwhatmay"y be called producer-gas, more particularly designed for fuelpurposes. l In my process and apparatus the operati-on o of producingor'making the gas is continuous.

It is not necessary to suspend the operation at intervals in order` toheat up .any part of it out vof' action every few rdays to clear outashes and clinker and build a fresh fire. The

fuel is fed continuously in onedirection, the alr-supply andresulting-gases passing con- Vtinuouslyv in the opposite direction.

My invention-has for its objects, first, to. se-

^ cure a continuous operation; second, to utilize coal-dust, which isnow practically a waste product, and, third, to substitute machinery-for manual labor.

Theapparatus provides for regulating the feed of pulverizedfuelthroughhot tubes or iiues, by which means it-is rapidly heated to a state ofincandescence and is thereby brought into `a condition for almostinstantaneous combustion when it reaches the combustion-chamber, inwhich it is vmingled With an opposing current of hot air.v It providesfor the heating of said tubes or ues and also forheating motingcombustion. It also Vprovides means for the mechanical removal of theash. yThe moving parts are all of suchcharacter as may be convenientlydriven from a commonsource of power; but it is intended that each shallAhave independent connections by `which its relative movement may beregulated.

The nature of. theinvention consists lof the My invention relates tocertain improvelarly pointed out by the claims.

Y Latitude is allowed herein as todetails', as

protected.V f the apparatus.' Neither is it necessary to put.

suitable chamber l, preferably an ironor steel 'closure rectangular ingeneral outline, with a provided in such chambers. Said chamber .l has ahopperl or receptacle 3, with a plurality or series'of' fuel-feedingperforations or oritices 3f through its bottom, and immediatelyvcombination and arrangement ofpartspincluding' their' construction,substantially as hereinafter more fully described, andparticuthey may bechangedas circumstances sugl gest without departing from the spirit ofmy invention and the samev remainintactand be In;carryingoutmyin'vention I-provide a lbelowand 'in contact with said bottom ,.is. a

.plate or partition 3b, forming the top of said 8O chamber'and having-acorresponding number of perforations -or orifices v3C registering withthe orifices-3a. are preferably rounded out upon. their .opposed edgesorsurfaces, thereby formingintermediate circular or cylindric seatsd,the purpose of which will next be seen. A series of cylindricaxially-rotatable valves 4 are ar ranged in the series of seats 351, one,valve being let into eachl series of alining seats and lprovided intheir opposite orl upper and lower surfacesy with alternating series ofcavities or recesses 4o 4b, each thus adapted to engageor Said seriesoforices 3 3 take a. prescribed quantity of the fuel or carbon in apulverulent condition from the hopper or receptacle '3 to provide forregulating.

the feeding of said carbon or fuel to the generator or producer, aspresently made more fully apparent. Each valve therefore controls anupper and a lower series of register- IOO effecting the feeding of thecarbon or fuel, or

said valves may be otherwise actuated.

Within the chamber 1 are disposed a series or plurality f partitions orplates 5 5 with their upper ends arranged in direct contact with theunder side of the top of said chamber and in planes intermediately ofthe oriiices 3", each two plates forming the walls of alternate verticaltubes 5, with which communicates each of said orifices, also the wallsofintermediate tubes 5, which, however, have `no direct communication withsaid orifices and tubes. Said tubes 5b communicate at the rear or back,near or at their upper ends, with or are extended linto a rearwardlyextending common tube or arm 6, in turn connecting with a commondownwardly-extending conductor or closure 7, itself being preferablyprovided at its lower end with a rearwardly-extending arm 7 forconnection with suitable means for delivering the gas to other parts forthe further treatment of the gas-as, for instance, a scrubber-or for useas fuel. Said plates or tubes 5 each depend within the chamber l to apoint .sion and elevating the ashes to a ,suitableY in a common planeand yet arranged a sufficient distance above or from the bottom thereofto provide a combustion-chamber 8. The lower end of said chamber hasfixed thereto, preferably as shown, a preferably tapering bottom orash-pit 8, adapted to constitute a water seal, and containing apreferably spiral or screw conveyer 9 to provide for the lateral andautomatic delivery or removal of the ash. Said tapering bottom orash-pit has a lateral extension, into whichthe shaft of the convey-erextends, and which shaft has fixed thereto'preferably a lsprocket wheelor pulley 9, encompassed together with a corresponding pulley 9,suitably supported by an' endless belt of buckets 10, dipping into saidash-pit extenpoint out of the way. A similar water-sealed ash-pit ll issupplied to the arm or extension 7 in alinement with the conductor orclosure 7 to receive any precipitated ash which may be carried over withthe gas` and falling through said conductor. Also a like spiral or screwconveyer 12 is arranged in said ash-pit 11, with a sprocket pinion orpulley 11 fixed to its shaft and arranged in a lateral extension of saidash-pit, an endless belt of' buckets 13 encompassing said pulley, also asecond pin-V ion or pulley 13, suitably supported in position, elevatingor removing the ash from said ash-pit.

In order to effect the initial heating of the retort or generator l,burner-tubes 14 are preferably provided, projecting through one side ofthe combustion-chamber and thcrei nto and connecting at their outer endswith a conimon head-pipe 14", in turn connecting with a pipe 14,leadingfrom asupply of hydrocarbon or other combustible fluid, the ignition ofsaid hydrocarbon or iiuid at the burner ends of said burners generatingheat in said combustionchamber for heating the plates or walls of thetubes 5 5".

For delivering or supplying air to the combustion-chamber of thegenerator or retort I provide a series of pipes 15, with one end of eachcommunicating with said chamber, about in alinement with or opposite theburnertubes 14 and preferably connected to a coinmon transverse pipe15". Said last-referred to pipe has connected to it a series of verticalpipes 15, in turn preferably connected to a second common transversepipe 15", and into -this pipe delivers or discharges a single verticalpipe 16, leading from a blast-fan orl generator 17 of ordinary or otherconstruction, suitably arranged or supported in position.

The combustion chamber having been fired or heated, as above pointedout, fuel or carbon, preferably supplied to the hopper, is delivered ordropped by suitably actuating` the carbon or fuel delivery valves 4f.into the tubes 5. Then the combustion-chamber and the various tubes 5 5hhave been heated suiiiciently to insure the ignition of the pulverulentfuel or carbon, the last named is fed slowly into the tubes 5,accompanied with a considerable excess of air from the fan 17 to suchextent as to produce complete combustion, which of course will aid infurther raising the temperature of the retort or generator. When thegreater portion of the lining is incandescent, the initial heatingaction is cut off and the required temperature maintained thereafter bythe gasification heat. At this stage the feeding of the fuel or carbonis increased rather rapidly or the air-supply correspondingly diminishedto bring about the relative proportional feeding thereof according tothedemand made upon the apparatus. The fuel in the hopper is maintained ata depth practically preventing leakage of `ing its conducting-pipe tothe action of the hot gases. It is also noted that anthracite IOObination of a fuel receptacle or hopper, a -plurality of vertical flues,tubes, or passages arranged to receive fuel from said'hopper, means forcontrolling the rate of feeding fuelv from said hopper into saidfuel-nues, la combustion-charnber into which the lower ends of saidfuel-nues deliver, and uptake flues or passages leading fromsaid'combustion-chamber and alternating with said fuel-nues.v
